The Back Office Segment includes one or more Back Office Servers (BOS), key exchange servers, other management system as well as the railroad dispatch system, other railroad backs office systems or applications, and the Locomotive and Communications Segments of the PTC system. The Back Office Segment is the source of mandatory directives and train initialization information generated by the railroad’s dispatching system and other railroad information systems, and provides electronic delivery to the Locomotive Segment. The interface between the Office Segment and the railroad dispatching and information systems may be proprietary to a particular railroad. However, the Office Segment translates the operating data provided by a particular railroad’s dispatching and information systems into industry standard formatted messages for exchange over an interoperable interface with the Locomotive Segment. This paper discusses the Back Office Segment interfaces and data requirements and what is required for a railroad or transit agency to plan and implement a functioning Back Office Segment for ITC type Positive Train Control Systems as either a Host or Tenant.
